Replaced 'Limits' with 'Notes'.
...
Quite some items in the 'Limits' sections aren't actual limitations so it seems appropriate to just use a more neutral term.

Match screen dimensions as in BASIC.

Experiments show that under BASIC by default
25 rows by 24 columns are used. 24 columns is
also the width that is fully displayed on a real
C1P on the monitor. conio now matches that now.

If kbhit() detects that a key is pressed, it fetches and
buffers the character. If cgetc() detects a buffered character,
this one is returned instead of fetching one with the PROM
routine.
